What is Spinel Jewelry?
Spinel gemstone includes a wide range of colors and designs available, and the abundance of Spinel in the market has made it one of the most affordable and luxurious gemstones on the market.
The use of Spinel in jewelry has a long history. Even in the past, people in west of Asia thought that the powerful spell of Spinel makes a person who wears Spinel clothes stay away from darkness and evil.
Spinel is a relatively hard gemstone that is recommended for use in jewelry making; because it is more durable due to its high resistance to environmental factors. Today, Spinel is found in many parts of the world, but depending on the location of each region, the Spinel obtained from that region has different appearance and physical properties. Different Spinel gemstones have different brand and scientific names, and this difference is due to the variety of colors and types of spinels in middle east and world.
Cinnamon spinel: This pumice stone is usually pinkish brown in color. This type of Spinel is mostly found in California, Sri Lanka, South of Asia, Brazil and the United States.
Green Spinel with Tsavorite brand: This Spinel has light green to dark shades and is sometimes confused with emerald. This type of stone is found in Tanzania, Kenya and Africa. If a combination of this stone with emerald is used in jewelry making; due to its great resemblance to emerald, it seems a little difficult to distinguish.
Espartite brand spinel: This type of Spinel is found in orange and has a range of bright yellow, orange and bright reddish orange colors, but each color spectrum has a different price compared to other colors. Spasitis is still found in many parts of the world, including the United States.
Demento brand: This type of stone is one of the very rich and vibrant types of green Spinel and is found in the Ural Mountains of Russia.
Demantoid spinel is very shiny and fiery and is very similar to diamond. This type of Spinel is very rare and has unique physical properties and is known as a very expensive piece of jewelry.
Rhodolite brand spinel: This type of Spinel is very similar to the rose and has a pink and reddish color that is found in North Carolina and the United States.
The beautiful color of this type of Spinel stone has made it a very suitable stone for use in jewelry.
Masai Blue Spinel: This type of blue Spinel was recently discovered in 1990 in Tanzania.
Its blue color and also the lack of this type of stone in the market, has made it a very valuable and precious pumice stone. Recently, however, specimens of this type of pumice have been found in the United States, Russia, Kenya, and Turkey, and these discoveries have reduced the price of this type of stone slightly.
Some types of this Spinel have the property of changing color and can be seen as purple due to the light of the lamp.
After selecting the desired color and type of spinel, by creating very beautiful cuts in them, very beautiful shapes of them can be used in jewelry making.

How to identify and detect spinel from ruby?
Rubies and red spinels are commonly found in mines. Due to their great similarity, the two minerals were not separated from each other until recent years, so most red pearls were considered rubies in ancient times.
In 1783, a French mineralogist named Louis Rom de lisle introduced pearl as a separate mineral from ruby. From a chemical point of view, ruby is a combination of aluminum oxide corundum (AL203) and magnesium aluminum oxide (MgAL204), while rubies are in a "hexagonal crystal" hexagonal crystal system. They form "Trigonal", forming Spinel gemstones in the isometric crystal system, "Cubic cube" and "Octahedral".
The density and light emission index of rubies are slightly higher than those of rubies, but this difference is so significant that it distinguishes the two seemingly similar stones. In fact, differences in hardness and weight helped ancient gemstone carvers in Sri Lanka, South of Asia and Burma understand the difference between rubies and spinels before gemology was introduced to the world as a science.
Where are Spinel Gemstone Mines and Reserves?
Myanmar, Tajikistan, Sri Lanka, South of Asia, Thailand, Vietnam, Cambodia have the best Spinel quality called "ruby". Other countries such as Afghanistan, Nepal, Australia, Tanzania, Madagascar, Nigeria, and southwestern Kenya also have good veins. In Vietnam, near the Luc Yen region, the extraction of spinels and rubies has begun in earnest since 1990, when most spinels are pink.
In Tanzania, in the 1980s, red-pink to cherry-red Spinel stones and a neon effect were found in mines around Morogoro County. Today, there are reports of clear, cut spinels ranging in size from 10 to 50 carats. Tanzania has been reported. But let's look at the most important places with reserves of this mineral:
Badakhshan Spinel (La’al) mine in Tajikistan and its history
The ancient and historical mine of Badakhshan (La’al Mountain) near the Murghab region in the east of Badakhshan province, whose spinels are known in ancient Iran as "La’al Badakhshan", is one of the most important deposits of La’al stone in modern Tajikistan. The mine is said to have been discovered due to a strong earthquake and the subsequent collapse of large rocks from the mountain and the damage caused by it.
At an altitude of 2,900 meters between Kurog and Vashkashim along the Panj River, on the border between Tajikistan and Afghanistan, is the La’al Mountain mine, which has about half of its spinels red and the rest pink. Mining of this mine started in the 7th century AD and it is said that famous stones such as Timur ruby and Black Prince ruby, which were originally spinel, were extracted from this place.
During the twentieth century, due to the geographical and closed conditions in the Soviet Union, these mines were less known. In the war between the Russian and British empires over colonialism and the demarcation of borders in western Asia, because Russia had little interest in jewelry, these mines were mapped on the Afghan-Russian border and somehow hidden from the world.
Sales Market Situation and Spinel Price
What is clear is that the price of this beautiful jewelry is increasing in the world. The price of this stone in large sizes can be very high and below its large samples are very rare. It should be noted that Spinel reserves are equally limited. For quality Burma and Tanzania samples, it can be as low as $ 200 to $ 500 per carat. For sizes up to 2 carats and pure red, the price is usually $ 600 to $ 1,200.
Similarly, by increasing the size, for example, 2 to 5 carats, 3 to 5 thousand dollars per carat will increase. Specimens with specific and rare colors and large sizes are also priced at up to ten thousand dollars per carat. What is obvious is the quality that determines the price of the spinel.
Spinel has a glassy sheen in its raw state; but the better and more accurately it is cut, the better the polish, to the extent that the polish is also upgraded to semi-hard (semi-diamond-like), which is an important advantage for Spinel. Transparent, brightly colored spinels with strong cuts are usually used to make jewelry, and more opaque, faded or opaque specimens are used to make spheres, symbolic pendants, and more.
Six methods to detect artificial spinel gemstones
Fluorescence: Natural pearls show strong fluorescence under high-wavelength ultraviolet light, and weak under short-wavelength UV. Fluorescence image of artificial Spinel rock under short-wave UV light
However, its synthetic varieties show strong fluorescence during short wavelengths of UV rays and often show light blue, gypsum green or red.
Microscope: Under the microscope in samples of artificial spinel, traces of flux melting or bubbles in the form of patterns and curves are usually seen due to the way they are made and grown. This is while in natural samples there are many or at least some inclusions.
Magnets: Natural spinels contain some element of iron and therefore react poorly to the magnet. However, in the synthetic and synthetic Spinel samples, there is no reaction due to the way they are made.
Production in the market: Synthetic spinels with dark red color due to the cost and complexity of the production process are made in small numbers and limited compared to other colors and usually these samples in the market of artificial corundum (ruby) and they are laboratory.
Light refractive index and specific gravity: Natural Spinel has a refractive index of 1.72 to 1.74 for the red Spinel and 1.805 when the zinc element is high. The synthetic spinners, on the other hand, have an RI of 1.727 with an error of one thousandth. Also, the specific gravity of the natural type is in the range of 3.58-3.61 and the zinc element in it can increase its specific gravity up to 4.40. This is while synthetic spinels have a specific gravity between 3.64 - 3.63.
Price: Synthetic Spinel rough can be from 300 to 800 dollars per kilogram depending on the quality of the manufacturer. Synthetic Spinel gem may be as much as one or two dollars per carat! Price is therefore an important factor in the detection of synthetic spinels. Synthetic samples are very glassy. You should note that the best way to identify the original Spinel is to purchase it with a valid gem certificate.
